1 Claim.

This invention relates to new and useful im'- provements in oil filterssuch as are used on automobiles, with the principal object of theinvention being to provide an oil filter employing a removable filteringcartridge which can be easily removed and replaced with but a minimum ofeffort.

Another important object of the invention is to provide a filter of thecharacter'described wherein the parts are readily accessible at alltimes for the purpose of repairs or replacements.

Another important object of the invention is to provide a filter of thecharacter stated which can be manufactured at less cost than most typesof filters nowin general use.

Other objects and advantages of the invention will become apparent tothe reader of ing description.

In the drawings:

Figure l is a side elevational view of the filter.

Figure 2 is a vertical sectional view through the filter.

Figure 3 is a cross-sectional view.

Figure4 is a side elevational view of the perforated cartridge. f

Figure 5 is a perspective view of the follower.

Figure 6 is a perspective view of the follower guide.

Figure 'l is a sectional view lower guide. l

Referring to the drawings wherein like nu merals designate like parts,it can be seen that numeralv 5 denotes a cylindrical shell, the loweredge portion of which is adapted to bedisposed into trough-likeformation AIi at the edge portion of a bottom 'I which has considerablepacking means 8 therein. Numeral Sdenotes a well depending from thebottom 'I and this has a nipple IIJ depending therefrom to whichl aconduit can be connected.

At the upper portion of the shell 5 is an inlet nipple II.

Numeral I2 generally refers to a cartridge which consists of aperforated container I3 having an opening in the bottom thereof throughwhich an elongated perforated tube I4 is disposed and suitably securedas by welding. The upper end of the tube I4 terminates slightly belowthe top of the container I3. The lower portion of the tube I4 has acircumferential rib I5 which can bear upon the bottom 'I when the lowereX- tremity of the tube is disposed through an opening in the bottom 1.

The top of the shell 5 has an opening therein and through this isdisposed an elongated tie rod I6 which extends downwardly through thetube the followthrough the fo1' I4 and through the well 9 and isequipped with a nutI'I at its lower end which can be tightened againstthe bottom of the well 9 to hold the parts firmly together.

Numeral I8 denotes a follower plate which is disposed within -the upperportion of the container I3 and has a central opening I9`through whichthe rod I6 is disposed. Also disposed through the opening I9 is a, shorttube 20 projecting from a washer 2|; A short skirt 22 depends from thewasher 2l and acts as a guide, snugly tting within the upper portion ofthe tube I4.

A coiled compression spring 23` is located on the upper portion of therod I6, same being interposed between the topv side of the followerplate .I8 and the under sidel of the top of the shell 5. A

Lifting lugs 24, 24 are provided on th of the follower plate I8.

Obviously, when the nut I'I is tight,y the parts are firmly heldtogether, and the spring 23 is urging the follower plate I 8 downwardlyagainst a, mass 25 of waste material, or other matter usually employedfor ltration, thus keeping the mass compact.

Obviously, when it is desired to refill the lter all that is necessaryis to remove the shell 5 from the bottom 1, thus releasing the containerI3, so that the material 25 can be removed from the container and freshmaterial inserted, after which the device can be put back together foruse.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, size,and

top side ,materials may be resorted to without departing Havingdescribed the invention what is claimed as new is:

A filter comprising an imperforate bottom hav-` ing Va trough-like' edgeportion and provided with a central opening, an imperforate shell openat the bottom and having a top wall, the lower end of the shell fittingin the trough-like edge portion of the bottom, said shell having aninlet near the top, a perforated tube disposed centrally of the shelland mounted on the bottom with its lower end depending through thecentral opening of said bottom, a, well carried -by and depending fromthe bottom and into which the lower end of the tube opens, said wellhaving a bottom outlet. a cylindrical filtering element mounted on thePerforated tube within and in spaced concentric relation to the shell,and a bolt extending through the top of the shell, the tube and thebottom of the well and having a nut threaded thereon for securing thoshell and bottom toaether. kaid Alteringelement including an open topperforated container extending above the tube and havin: a quantity ofwaste therein. a washer reatlng on the upper end of the tube and havin:a

vdepending skirt tted in the upper portion of sold tube, a tubular cuiderising from the washer and ALBERT THOMAS PARRY.
